Any device that is classified at 240 volts and can also be used in a 220V or 208V output. A local motor supply shop had some interesting information on this. A. either way i would think you'd have some sort of mechanical reaction from the motor … There is a good chance that it is also a 50Hz motor in which case running it on 60Hz is going to make it run 20% faster and possibly heat it up a bit in the process. Hi, We are planning to do an event at an hotel where we've been advised all they can provide is 208v. 230V (the actual nominal supply voltage is 240V) is probably too high for that motor. The rest: 220, 230, 240, & 250 are all collectively (and in a sense erroneously) used to describe 240. 208V is typically found in three-phase systems, mostly found in The single phase to 3 phase VFD is the best option for a 3 phase motor running on single phase power supply (1ph 220v, 230v, 240v), it will eliminate the inrush current during motor starting, make the motor run from zero speed to full speed smoothly, plus, the price is absolutely affordable. thanks « Last Edit: January 15, 2013, 06:23:04 am by e2e8 » I have a question about running a 230/430V 3phase Baldor vector motor on 208V 3phase through a Mitsubishi V200E vector drive.

If the service was a pure 208 volts, at a minimum, then the motor would … Look on the motor plates of your equipment for the voltage spec... a lot of single phase motors will say 208-220V on them, and you *might* be able to re-link them to work better on the lower voltage. Did I take good precautions  to prevent frozen pipes? It may be for just that voltage. What does contingent mean in real estate? 208 volts = 2.9 amps 240 volts = 3.6 amps On their shelf, they had another 208 volt motor that was brought back for warranty. Im trying to run this motor but it doesn't budge and I don't even hear a hum. If your phase converter is actually putting out 220V you should be fine, but I suspect if your power is anything like mine, you will be closer to 240V. which means that yes an electric motor designed for 230 volts can run on 208 volts. Join Yahoo Answers and get 100 points today. encompassing both but equipment with motors will have trouble The only one different in the list is 208v. But when they do that, if you use 208V and the line drops by 10%, NOW you are outside of the design tolerance. Can I run a motor at 208v 3 phase if it says 220v on motor nameplate? degrees out of phase with each other. Most motors that are rated at 230 volts will run on 208 volt power, although this is not recommended. for the higher end will not work to but about 75% of capacity when I would wire it up and put an amp probe on it, if the current draw is within reason, you should be fine. - Answered by a verified Electrician. It talks about 208v. if the motor is calling for 208 then 220 should work if thats what you have. It is most likely a 380V motor. Will a 220v motor run on 208v? In most cases nippled right of the panel feeding the equmient. Most modern motors are rated 208/230 whether they are single phase or 3 phase. Most AC motors are built to tolerate a 10% variation from nameplate voltage. Most of the time you see 208 volts on 3 phase and 230-240 on single phase. or 240v. So since there will be no current in this neutral wire I will use it as the chassis ground. 220V (actually 240) is a single phase system Because motor voltage tolerances are typically +- 10%, some manufacturers will build to a base design of 220V, then label it 208 - 230V, because 220 * .9 = 198 and 220 / .9 = 244, so they are covered both ways. Can I just hook it up to the old circuit 208v circuit? distribution. However, most electronics are generally run on 110/120 in the US getting full performance out of that large a range, heaters sized range. The 220v wiring is used for some refrigerators, washers and dryers. Most kitchen appliances are classified at 240 volts. commercial settings. 220-230-240 (depends on utility) is the standard nominal 1-phase voltage across both legs of the line (120 nominal being the voltage from either leg to neutral). 208 is the net voltage developed The rated voltage is 240 volts, but the boxes can have a power supply of 208V, 220V or 240V. This is a NEMA requirement. which are 180 degrees out of phase. 220v.? The lower 110v wiring is used for most standard appliances and devices, such as computers, TVs and table lamps.

Using equipment rated for 208 an ABC rated fire extinguisher would be appropriate for use on buring wood? I have a motor thats rated for 220V single phase. If the motor has only the one voltage on it, you may want to question the manufacturer or try to get your old motor back. Operating a motor rated at 230 vac on 208 vac will cause the motor to operate at a higher temperature and slightly less HP will be produced. There are problems and a potential for confusion, but substantial savings are available and the resulting "band-aid" will surely function longer than the load equipment. The nameplate on it says it's a 220V machine, but there's a label that the installer apparently put on it which says it was converted to run at 208V. If you want to do the proper thing, get yourself a pair of buck/boost transformers to boost your voltage to 230. in a residence where its split single phase - 110/120 between Will a 220v motor run on 208v? Aren't ovens, dryers, etc. If the motor has only the one voltage on it, you may want to question the manufacturer or try to get your old motor back. And in response to the other post about “where does 208V come from” – in my experience the more unusual voltages are usually related to 3-phase power, which is another option you will see in datacenters. Since a standard three phase motor can be 200 or 230V, most know that 230V is no good for 208V nominal systems, and Tom quoted 110.4 which doesn't permit a 200V on a 208V system, what's a person to do? They tested a Baldor 3 phase, 208 volt motor at 208 and 240 volts, under no load. how do i determine capacity of kenmore refrigerator. Why does resistance increase when current decrease? Some equipment may be made with an acceptable input range Most devices designed for 220 will run on 208 and in shops all over the place this is commonly done. 220/240 is the distribution The range for a 230 volt motor is 207 to 253 volts. The individual legs are 120V to neutral and 120 It will run, but how hot it may get are depend on many factors, specific to each situation. Most modern motors are rated 208/230 whether they are single phase or 3 phase. I am looking at a steam generator for a shower. Motors are rated for 10% over or under the nameplate voltage listed on the motor. I have seen aplications were they require 220v to operate if so a buck-boost is cheep and quick. I think with expected voltage drop, you could use judgement, since of course we do place 200V motors on 208V systems. The 208V is in essence a Who is the longest reigning WWE Champion of all time? Who does Demetrius play for in a midsummer nights dream? regulators are now common that will handle this range, though. I got a 220V Rancilio Classe 10 SDE2 from a Borders cafe that was shutting down. single phase voltage when used as such. When a motor is rated at 208/230 volts this means the motor will operate at the 208 volt rating, not 10% under the 208 volt rating. How long will the footprints on the moon last? Your motor is rated at 200V at its terminals to allow for some drop between your service entrance, through feeders, branch circuits, etc. either hot leg and neutral, and 220/240 across the two hot legs A few years ago, I had a situation where I was called for problem at a school that was maybe 1-year old, which had 3-phase 208V service, and a large well water pump wired by the original EC that was designed for 240V. Is the 208v a european voltage?Also, I hear most people refer to 220v but here they talk about 240v. At 60Hz, the motor will run at 20% higher speed than it would at 50Hz , so it may require a further 20% increase in voltage. many motors have a 10% allowable variance between supply and utilization voltages. if you truly have 240 volts then there is definitely an issue. An quick internet search reveals several sources that all say no, but I am concerned that the people answering the question don't know what they are talking about - as is often the case on the internet. typically found in most homes.

Most newer motors will run 208-240 just fine. A 230 volt motor running on 208 volts will run … Even though the system voltage of 3 phase 208 is within the -10% rating of the three phase 230 v motor, the 208 is allowed to vary to -10% or 187 volts -- and the motor will not work at that level. Electronic equipment with switching That will not play nice on your 208V service unfortunately. Design of the 208V motor should be rated for +10% in voltage which puts you at 229V, but if your RPC is running at 245V out, your a little further than the range +10% Overheat could be possible, coupled with extra heat from not perfectly balanced voltages from the RPC. since they don't require high power. You will probably be replacing that motor often if you run it at low voltage. 3] I assume the motor is 3 phase.... 4] While synchronous motors will run on a slightly lower voltage, if grossly undervoltaged they will burn out. It will probably be fine but it wouldn't hurt to question it. I need to know if a 240 volt ac squirrel cage fan motor can be safely run on 120 volts ac. While most of the world uses 220-volt electricity, the United States uses a combination of 220v and 110v appliances. between any pair of the three legs of a 120V three phase And it follows all down the chain – you pay more for a single power strip and need far fewer of them, you run wire that is slightly thicker diameter, but only need 1/4 as many runs. Doing so will shorten the life of the motor though. OP: “What if I plug a 220V to a 240V?” This question is not well worded, and depending on that the original author was thinking, missing some details. If my understanding of inverters is correct, the motor will never see even a full 208 volts except at maximum frequency from the inverter. My house has 240V single phase. The motor will not run at it's optimal performance level but it can be operated at this level. It's been my experance that a 220v load 1 phase (induction motor) will run just fine on 208 1 phase. Regulator on Central Pneumatic air compressor not giving proper air.? We would be running a Rancilio Classe 7 that requires 220v-240v along with 4,300W. A motor designed to operate at 220v will not normally operate at 208v correctly unless it is a multi-voltage motor and then when it is wired the leads are wired in a different pattern. volts but used at higher) and incandescant bulbs will burn out What's the difference?Thanks Another concern is the motor appears to be for a 50Hz three phase power supply, but the power supply on site could be at 60Hz 208v, so we must take that into consideration, too. This is why brownouts fry appliances. Is Los Angeles under a government consperiecy for a massive depopulation by your own military?
